The method putStringExtra(String, String) is undefined for the type Intent

问题

I am trying to fix an issue I do not understand. I get an error "The method putStringExtra(String, String) is undefined for the type Intent" in line 4 inside my onItemClick method. What could be the reason for this?

public void onItemClick(AdapterView<?> adapter, View arg1, int position, long arg3)
{
    String item=adapter.getItemAtPosition(position).toString();
    Toast.makeText(Activity.this, "You Click on:"+item, Toast.LENGTH_SHORT).show();
    Intent intent = new Intent(this, MyOtherActivity.class);
    intent.putStringExtra(MyOtherActivity.TEXT_TO_DISPLAY, item);
    startActivity(intent);
}

Just use Intent.putExtra(). There is no method putStringExtra() on Intent. It knows what the type of the parameter is and adds the extra with its type.
